Letters. .Patent No. 106,917, dated August 30, 1870.

IMPROVEMENT IN AUTOMATIC GATES.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

Be it known that 1, JAMES B. (BOTTOM, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements lin Automatic Gates; and I do hereby declare that Figure 1 of the drawing represents a perspective view of my. improved gate; Y Figure 2 represents the gatel adjusted and Figure 3 is a sectional elevation.

VMy present invention relates to certain improvements upon the invention for which my application for Letters Patent was tiled in the United States Patent Oce, January 4, 1870 and consists in the combination ot' an adjustable hinge with the elongated lower crank of the pivot-shaft by which the .gate is hung.

The gate A, posts B C D, rods E, angle-irons G, and the other parts of the structure, except the pivotshaft N and hinge `X, do not essentially differ from the same-devices which were described in my application of January '4, 1870, above referred to. And the operation of the gate by a passing vehicle, the wheels of which will actuate the angle-irons Gr, to open and close the gate, is substantially` the same as described in my-said former application.

The pivot of the upper hinge X is connected with a collar, X, seen in tig. 3, andthe collar is adjustable upon shaft N. The crank O is elongated upon shaft N, so as to admit of the adjustment of the collar X', by which the gate maybe raised up and secured upon pivotshaft N at any desired elevation, by the thumb-screw, which passes through the collar X', ,as seen in fig. 3 of the drawing.

The object of the adjustment is to adapt the gate to be freely opened and closed when the ground over which it swings-is obstructed by snow, or from other causes.

Having fully described my improvements in alitomatic gates,

What I claim, and desire to-secnre by Letters Patent, is

The combination of' the adjustable hinge X X', with the pivot-shaft N, provided with the elongated crank O, substantiallyyas'and for the purpose described.

In testimony whereof I have hereunto set my 4hand this 19th day of' April, 1870.
